Interestingly, the fluorescence emission spectra show that the fluorescence intensity of the organic-inorganic hybrid is partly quenched compared to pristine porphyrins, indicating possible energy/electron transfer between POMs cluster and porphyrin under light irradiation. Their UV-vis diffuse reflectance spectra show an extended absorption in the visible-light range. Finally, the as-prepared photoresponsive hexavanadate-porphyrin molecule is proved to exhibit effective photocatalytic activity toward removal of rhodamine
